A tokamak plasma rupture simulation device and simulation method

Abstract

The invention discloses a Tokamak plasma disruption simulation system and a simulation method. The device comprises a power supply capacitor, a discharge switch, a freewheeling diode, an ohmic coil, a core, a plasma coil, a disruption simulation switch, a disruption simulation resistor, and a trigger control unit. The power supply capacitor is used for supplying power to the ohmic coil and inductively generating a current in the plasma coil. When the discharge switch is switched on, the power supply capacitor discharges electricity to subsequent circuits. When the discharge switch is switched off, the power supply capacitor does not discharge electricity, and the voltage of the power supply capacitor remains unchanged. The freewheeling diode is used for constituting a loop with the ohmic coil after the discharge switch is switched off, and providing after flow for the current of the ohmic coil. The ohmic coil is used for simulating an ohmic field coil of a Tokamak device, supplying power to the ohmic field coil through the power supply capacitor, and inductively generating and controlling and maintaining a plasma coil current in a secondary plasma coil. The plasma coil is used for simulating a plasma current loop of the Tokamak device, and the current in the coil is used to simulate a plasma current.

Description

technical field [0001] The invention belongs to the field of magnetic confinement nuclear fusion plasma rupture, and more particularly relates to a device and a simulation method that can be used to simulate the plasma rupture process of a tokamak. Background technique [0002] During the normal discharge process of the tokamak device, the ohmic field coil and the plasma current ring constitute a two-winding transformer structure, and the primary ohmic field coil is powered through the power supply, so that a certain ring voltage is induced in the secondary vacuum chamber to generate plasma current. After the plasma current is generated, according to the principle that the current of the primary side of the transformer is proportional to the current of the secondary side, increasing the current of the ohmic field coil can pull up the plasma current, and when the plasma current rises to the preset value, the value remains unchanged , that is, the flat top of the plasma curren...
